I have this lovely thing running on a Raspberry pi 1 B. I have installed Jessie in order to run Python 3.4 which is needed. Moded the pin numbers, that is not the Gpio numbers, to match the old pi.
Thanks to KobiSnir

Why relay 1 is not working on my iphone. When I press the button it is not changing its state and also no output on GPIO pin 7. But on the server is changing out either 1 or 0 state
Appreciate if you can help me.
